To alli/11mm it may concern:

Be 1t known that we, CHRISTIAN E. P. Gumrr and CHARLES F. Scrinipmnu,'former subjects of the Emperor of Germany, who

-tion -of this character for preventing unauthorized removal of:in-automobile.

The invention consists in the combinations and arrangements of partshereinafter `described and claimed.

The invention will be best understood by reference to the' accompanyingdrawing forming a part of Vthis specification, andin which,

Figure 1 is a sectional view illustrating a lock embodying ourinvention, Fig. 2, a section taken at right angles to Fig. 1, Fig. 3, asection taken on line 3 3 of Fig. 2, and Fig. 4, a. detail view showingacain member employed in the-construction in a different Vposition fromthat illustrated in Fig. 2.

The preferred forni of construction as illustrated in the drawingcomprises an ordinary gasolene tank 5 mounted in the car in the usualmanner, and provided with` a discharge pipe G leading from the, bottonithereof. Discharge pipe. (j connects with a valve casing 7 arrangedwithin a protecting casing S located around the saine. .Valve casing 7-is provided with a. discharge pipe fl `leading to the engine of theautomobile, and

a reciproeatory'plug valve 10, as indicated. YValve 10 is provided witha. valve stem 11 'having a lslotaind pin connection 12 with an ar'in 123provided with an eccentric strap 14 engaging an eccentric 15 on anoperating shaft 1G, a compression spring 11 being interposed between thelower end of arm 1 3 and a collar 12 on valve stem 11. By thisarrangement, it will be observed, that valve 10 may be opened or closedby turning shaft 1G .in either direction and that a yielding `connectionis aiorded between the. eccentric Specification of Letters Patent.

`15 and the valve 10 lholding said valve to its seat.

Shaft 16 is provided with a lockingcam' Cam member 17 cooperates with aspring bolt 2i) of an ordinary combination lock 21, said bolt beingprovided witha notch 22 adapted to receive lug 18 and engage withshoulder 19, as indicated. The lock 21 is provided with the usualoperating knob 23 and shaft 1G is provided with au operating handle 24,as Shown.

By this arrangement. it will be observed, that when valve 10 iselosed,lug 1S engages notch 22 in bolt 20 so that if thel combination oflock 21 is thrown thesupply of i gasolene is cut off from the engine andcan only be renewed by oner knowing the com` bination of lock 21. Toopen the valve, the combination of lock 2 1 `is set and bolt 20withdrawn, whereupon shaft 1G maybe rotated through substantially onehundred and eighty degrees, and shoulder.v 19 engaged with notch 22, 4asindicated in Fig. t. thus holding the valve open. Then it is desired toclose theI valve, all that isuecessaryis to rotate shaft 1Gcounter-clock-haiid-wise, when cani surface 19 will automaticallyv dis`engage shoulder 19 from notch 22 and lug 1S will automatically engagewith said notch to lock the valve. in closed position when thecombination is thrown.

lVhile we have illustrated and described the preferred forni ofconstruction for earryingr our invention into effect, this is capable ofvariation and modification without departing from lthe spirit of theinvention. \Ve, therefore, do not wish to be limited to the precisedetails'of construction set forth. but. desiie to avail ourselvesof-such variations aiul modifications as come withinithe scope of theappended claiin.

side with a projection having abrupt shoul- 'ders on each-side thereofand'adapted to engage and interlock with said notch and at its otherside with a projection having an abrupt'shoulder at one side adapted toengage and interlock with said'notch and a cam surface at the other sideadapted to force back said bolt ,upon rotation of said shaft in onedirection, the arrangement being such that said first mentionedprojectionengages said notch when said valve is closed andy said secondmentioned projection engages said notch when said valve is open,substantially as described.

In testimony whereof we have signed our 15 names to this specificationinthe presence of two su'bscribin Witnesses.
